Newly discovered heart stem cells make muscle and bone

Researchers have identified a new and relatively abundant pool of stem cells in the heart. The findings in the December issue of Cell Stem Cell, a Cell Press publication, show that these heart cells have the capacity for long-term expansion and can form a variety of cell types, including muscle, bone, neural and heart cells. The researchers say the discovery may lay a foundation for much needed regenerative therapies aimed to enhance tissue repair in the heart. The damaged heart often doesn't repair itself well because of the incredibly hostile environment and wide-scale loss of cells, including stem cells, after a heart attack. "In the end, we want to know how to preserve the stem cells that are there and to circumvent their loss," says Richard Harvey of the Victor Chang Cardiac Research Institute in Australia
